EFFECT OF SPRAYING POTA CRASTAL COMPOUND AND VAST TRIVALIOUM COMPOUND ON GROWTH AND NUTRITIOANL STATUS OF SUPERIOR GRAPEVINES

This study was carried out in three seasons 2019, 2020 and 2021 to examine the effect of spraying Pota crastal or Vast trivolium compounds each at 0.1% either once, twice or thrice on growth and vine nutritional status of Superior grapevines grown under El-Minia region. Application of Pota crastal or Vast trivolium compounds once, twice or thrice each at 0.1% was very effective in enhancing main shoot length, leaf area, wood ripening coefficient, pruning wood weight/ vine, chlorophylls a , b , total chlorophylls, total carotenoids, N, P, K, Mg (as %) Fe, Mn and Zn ( as ppm) of superior grapevines over the control treatment. Using vast trivolium compound was favourable in enhancing some characteristics of vegetative growth and vine nutritional status rather than application of Pota crastal compound. The improvement in the growth characteristics and vine nutritional status was associated with an increase in the number of spraying times from one to three times. The best results with regard to character growth and vine nutritional status of superior grapevines grown under El-Minia region were observed due to treating the vines three times during each season at growth start, just after berry setting and at one month later intervals with vast trivolium compound at 0.1%
